:l for replacing worn parts Without uncoupling the threaded pipe connections through which 'water is supplied to the flush box; to provide slidably convenable parts in a check vvalve for vobviating the use of joints which are susceptible to'binding when they are exposed to cor- `rosion; and toprovide improved guiding structure for the movable valve memberof a check valve which is adapted to predetermine the maximum throw of the movable valve 7 member.

`An illustrative embodiment of my invention is shown in the accompanying drawings, wherein: p

Figure 1 is a vertical section of my improved check valve. y

Fig. 2 is a horizontal section taken on the line 2;-2 of Fig. 1." Y

Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 1.

Fig. 4 is a side elevation showing the valve parts in position to be disassembled. y

Fig. is a vertical section of another form of my invention.

In the form shown, the improved check valve includes a valve body having a seat on which is mounted a valve comprising a stem.. Extending upwardly from the 'valve body 1s a support which carries a pivotally mounted valve actuating member and a guide for the valve stem.

In the illustration shown, the valve body 1 comprises a tubular member having threads y 2 for securing it to a water inlet pipe of a flush boX not shown in the drawings. upper end portion 3 of the valve body is provided with Van integral neck `on which is mounted a valve seat 4 comprising rubber or other suitable material.

A valve 5 having a valve stem 6 at one end and a bell-shaped tubular housing 7 at its other end is slidably mounted on the valve body 1. The sides of the housing 7 are spaced from the sides of the valve body 1, by lugs 8 iormed on the inner periphery of the housing.

The

In the form of my inventiony shown in Figs. 1, 2, and 3, the valve body 1 carries an integral upright'support or post 9 on which a valve actuating member 10 is mounted by a pivot 10.1. One end of the lever `l0 extends into a slot 11 in thevalve stem 6 and the other end of the lever Vis secured to a float 12of the type generally used to lcontrol i flush bof; check valves. The support 9` extends upwardly substantially to the end of thefvalve stem 6, the endportion 13 of the support biing substantially elliptical in shape,`ras' shown inFig.2.V Y'

Mounted on the flattened end 17301 the support 9 is a U-shaped guide member 14, cornprising tubular material, one end of `which is formed to receive the flattened end portion 13. The other end of the tlf-"shaped guides 14 hasa guideway 16, linto which the.

valve stem 6 extends. The guideway 16? isA 7 retained substantially in alinement valve body 1 by the lattened end portions and 15 of the post 9 and guide member y14.1%;-

spectively. f The valve stem has a shoulder 17 which engages the extremity 18 of the guide member 14 and predetermines the maximum throw of the valve. a i Y y i l i When the level of the water in the flush box recedes, the float 12 is lowered-,thereby raising the valve and allowing waterlto downwardly betweenthe sides of the housing 7 andthe valve body' lintoV the flush box.

With the form of my invention shown in Figs. 1 to 4 inclusive, access may be had tothe valve parts, and' particularly to the valve seat 4, by first removing the U-shapedV guide 14, and thentilting the valve 5' to the left as shown in Fig. 4, until the valve ,stem 1 clear of the end of the lever 1Q. 'I fhe pivot 1.0.1 may also be removed to allow detachment ef the lever 10 and `float 12- if desi-red, but ordinarily when the valve 5 is removed the valve seat 4 may be replacedwithout further disassembling. the device. A Y

rIhe plug and socllet oint between the gui'd-e 14 and theA supportV 9 obvi'atesy the` use ofthreaded connections between the parts of the check valve and thereby prevents, binding and adhesion between such parts, which are normally exposed to corrosion.

In the form of my invention shown in Fig. 5 the support 9.1 and the guide 14.1 are integral. The support 9.1 comprises a metal tube having a ring 2O on its lower end through which the valve 1.1 extends. A thumb screw 21 extends transversely through registering apertures in the support 9.1 and the ring 20 and bears at its end against the side of the valve body 1.1. The screw 21 may be tightened to hold the support in a iixed position relative to the valve body. The valve 5, is slidably mounted on the valve body 1.1 between the guide 14.1 and the valve seat 4.

With this form of my invention the support, guide, float and lever may be removed as a unit from the flush box by loosening the screw 21 and sliding the ring 20 and support k9.1 upwardly over the end of the valve body.

Although but two speciic embodiments of this invention are herein shown and described, it will be understood that numerous details may be altered or omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. A valve for a water closet flush box comprising a valve body having a valve seat, a support on one side of said valve body, a downwardly extending olset arm on said support having a guideway therein substantially in alinement with said valve body, a valve slidably mounted on and downwardly overlapping said valve body, and a stem on said valve extending into said guideway, for retaining said valve in alinement with said valve body.

.2. A valve for a water closet flush box comprising a valve body having a valve seat, a support on one side of said valve body, a detachable yoke on the end of said support having a guideway therein substantially in alinement with said valve body, a valve slidably mounted on said valve body, and a stem on said valve extending into said guideway, for retaining said valve in alinement with said valve body.

3. A valve for a water closet flush box, comprising a valve body having a valve seat, a valve on said valve body comprising a stem, a support on said valve body having a flattened end portion', and a U-shaped guide member having a socket in one end for receiving said flattened end portion and a guideway in the other end for receiving said stem.

et. A valve for a water closet flush box comprising a valve body having a valve seat, a valve slidably mounted on said valve body comprising an upright stem, an upright support on said valve body, and a Ueshaped guide on said support having a socket in one leg for receiving the end of said sup- 65 port and a guideway in the other leg for receiving said stem, the top portion of said support and the opening in said socket being correspondingly shaped for retaining said guideway in alinement with said stem.

5. A valve for a water closet Hush box com prising a valve body having a valve seat, a support on one side of said valve body, a downwardly extending offset arm on said support having a guideway therein substantially in alinement with said valve body, a valve slidably mounted on said valve body, a stem on said valve body having a slot therein, said stem being slidably mounted in said guideway, and an actuating lever pivoted on said support and extending into said slot for moving said valve vertically relative to said seat.

6. A valve of the class described comprising a valve body having threads at one end for attaching said body to a water supply pipe, a neck on the other end of said valve body, a valve seat on said neck, a valve comprising a central chamber having a conical end for receiving said valve seat, a stem integral with said valve, a support integral with said valve body comprising an upright post extending substantially to the end of said valve stem, a flattened portion on the upper end of said post, and a removab-le guide member detachably mounted on said post comprising aA flattened tubular extremity for receiving the end portion of said post and a substantially cylindrical tubular extremity for receiving the end of said sleeve.
